The entrance into the Magic Kingdom is a street conveniently lined with shops (neat shops, but shops nonetheless). This street is Main Street, U.S.A. at the two American parks. The street leads you directly to the central hub. From there, you can visit the other lands.

Space Mountain. Indoor, low-light roller coaster with no inversions, but in the darkness you can't really tell anyway. Infamous for many years as the ride with the longest line (although Splash Mountain usually holds that distinction now).

There are scores more attractions, of course, but the differences among the parks start to become more apparent. Despite what people say, the Magic Kingdom really is a magical place, especially for kids. But only the most cynical of grown-ups would be unable to have fun right along with them.
